Commit 63f534b8bad9 ("ACPI: PCI: Rework acpi_get_pci_dev()") failed
to reference count the device returned by acpi_get_pci_dev() as
expected by its callers which in some cases may cause device objects
to be dropped prematurely.
Add the missing get_device() to acpi_get_pci_dev().

Recent commit 52fde2c07da6 ("nvme: set dma alignment to dword") has
caused a regression on our platform.
It turned out that the nvme_get_log() method invocation caused the
nvme_hwmon_data structure instance corruption. In particular the
nvme_hwmon_data.ctrl pointer was overwritten either with zeros or with
garbage. After some research we discovered that the problem happened
even before the actual NVME DMA execution, but during the buffer mapping.
Since our platform is DMA-noncoherent, the mapping implied the cache-line
invalidations or write-backs depending on the DMA-direction parameter.
In case of the NVME SMART log getting the DMA was performed
from-device-to-memory, thus the cache-invalidation was activated during
the buffer mapping. Since the log-buffer isn't cache-line aligned, the
cache-invalidation caused the neighbour data to be discarded. The
neighbouring data turned to be the data surrounding the buffer in the
framework of the nvme_hwmon_data structure.
In order to fix that we need to make sure that the whole log-buffer is
defined within the cache-line-aligned memory region so the
cache-invalidation procedure wouldn't involve the adjacent data. One of
the option to guarantee that is to kmalloc the DMA-buffer [1]. Seeing the
rest of the NVME core driver prefer that method it has been chosen to fix
this problem too.
Note after a deeper researches we found out that the denoted commit wasn't
a root cause of the problem. It just revealed the invalidity by activating
the DMA-based NVME SMART log getting performed in the framework of the
NVME hwmon driver. The problem was here since the initial commit of the
driver.

NVMe uses PRPs for data transfers and has no specific limit for a single
DMA segement. Limiting the size will cause problems because the block
layer assumes PRP-ish devices using a virt boundary mask don't have a
segment limit. And while this is true, we also really need to tell the
DMA mapping layer about it, otherwise dma-debug will trip over it.

Commit 27cfde795a96 ("RDMA/cma: Fix arguments order in net device
validation") swapped the src and dst addresses in the call to
validate_net_dev().
As a consequence, the test in validate_ipv4_net_dev() to see if the
net_dev is the right one, is incorrect for port 1 <-> 2 communication when
the ports are on the same sub-net. This is fixed by denoting the
flowi4_oif as the device instead of the incoming one.
The bug has not been observed using IPv6 addresses.

Currently netfilter's rpfilter and fib modules implicitely initialise
->flowic_uid with 0. This is normally the root UID. However, this isn't
the case in user namespaces, where user ID 0 is mapped to a different
kernel UID. By initialising ->flowic_uid with sock_net_uid(), we get
the root UID of the user namespace, thus keeping the same behaviour
whether or not we're running in a user namepspace.
Note, this is similar to commit 8bcfd0925ef1 ("ipv4: add missing
initialization for flowi4_uid"), which fixed the rp_filter sysctl.

It's possible that the driver will dereference a qcq that doesn't exist
when calling ionic_reconfigure_queues(), which causes a page fault BUG.
If a reduction in the number of queues is followed by a different
reconfig such as changing the ring size, the driver can hit a NULL

Fix this by checking to make sure both the qcqs array and qcq entry
exists bofore trying to use and free the entry.

==================================================================
The test fuzzes an rmap btree block and starts writer threads to induce
a filesystem shutdown on the corrupt block. When the filesystem is
remounted, recovery will try to replay the committed rmap intent item,
but the corruption problem causes the recovery transaction to fail.
Cancelling the transaction frees the RUD, which frees the RUI that we
recovered.
When we return to xlog_recover_process_intents, @lip is now a dangling
pointer, and we cannot use it to find the iop_recover method for the
tracepoint. Hence we must store the item ops before calling
->iop_recover if we want to give it to the tracepoint so that the trace
data will tell us exactly which intent item failed.
